What is the main purpose of a transformer in distribution equipment?

The primary function of a transformer in distribution equipment is to change voltage levels to appropriate values for distribution. This is crucial in electrical systems because power generation typically occurs at a higher voltage to reduce energy loss during transmission over long distances. However, the voltage must be stepped down to lower levels before it can be safely distributed to homes and businesses.

Transformers achieve this by using electromagnetic induction to transfer electrical energy between two or more coils of wire. The ratio of turns in the primary coil (input) to the secondary coil (output) determines whether the voltage is increased or decreased. By adjusting these voltage levels to suitable standards, transformers play a vital role in ensuring the efficiency and safety of electrical distribution networks.
